Panic - Watchdog Timeout: no checkins from watchdogd in 185 seconds

Most of the time I reboot my MBP 15-inch Mid 2014 with macOS Catalina 10.15.3 I get this... I tried PRAM and SCM reset but it comes back.


panic(cpu 2 caller 0xffffff7f88f3aaae): watchdog timeout: no checkins from watchdogd in 185 seconds (719 totalcheckins since monitoring last enabled), shutdown in progress

Backup.

Go to https://support.apple.com/downloads/macos and look for 10.15.4 COMBO update.

Download and run it.


Also some types of External monitors still cause kernel panics.

This has happened on my Mac Pro ever since I received it in May and nothing seems to fix it. It will go a week (sometimes 2) and then it starts shutting down or rebooting every time I'm not using it for 2 or 3 days and then goes back to normal. Sometimes it will boot to the login screen and only sit there for a moment before restarting or rebooting. Sometimes after shutting down the system is dead as a doornail for 10 minutes before it will restart. Just so you know, I spent about two months working with Apple enterprise (June and July while running Catalina, now I'm on Big Sur) trying to get this resolved and sent them many many diagnostics. We decided it was probably a hardware issue . I took my Mac Pro to an Apple repair shop and left it there for the month of August. They said they couldn't reproduce it. Funny, as soon as I got it back it rebooted before I managed to even log in. Now we've talked Apple into replacing the graphics MPX module (W5700X) since the log files have a GPURestart error a dozen times before every shutdown. My point is that I'm thinking this watchdog shutdown isn't caused by just one thing. I think there are various possible things that cause it. Clearly most people having this issue have different hardware than I do and very few have the W5700X MPX module, so that is not the common thread. I do run my LG 5k monitor off from USB-C. However I swapped it out for my wife's LG 4k HDMI monitor and it still had the shutdown/reboot issue. I've done clean installs of Catalina and Big Sur and no other software with no luck. I'm out of ideas.

It is good your employer saw sense in the end. Third party security apps always cause problems on Macs which have three level security built in.

The place for A/V in an enterprise is in the enterprise mail servers and firewalls to protect the Windows kit.
